About Seat Posts

A good quality seat post will save weight and hold your saddle securely. Seatposts are made in various materials, alloy and carbon being the two most common, alloy posts are lightweight, durable and cost efficient, while carbon posts are the popular choice for top end machines. Seat posts vary in where they hold the saddle relative to their own centre line so make sure you have enough adjustment on your saddle rails to allow for this or you could end up with your saddle too far forwards. A seat post needs to fit your frame exactly and are measured by as little as 0.2mm. When choosing a new one, either read off the measurement from your old seat post or measure it carefully with a vernier calliper. Make sure you lubricate the frame (unless they're carbon fibre) before insertion or you'll struggle to get it out again.

About the USE brand

USE have got an unhealthy devotion to perfecting the ride experience because, well because riding is what they're about & they figure that if they develop new gear they get to test it, which means more riding & frankly that's the sweet spot.

Answer:

I can confirm that all of these shims are designed for use with a 25 mm seat post and will increase the post to the selected diameter. Unfortunately these will not be suitable for use with any other seat post diameter other than 25.0 mm.

Answers

Answer:

Shim goes into seat stem. If you have a 25.4mm then the size shim you need is the 25.0--25.4. But check this again because the seat posts come in 25 and 27.2. A 25mm post should fit your bike without a shim and the 27.2 post will not fit ever.
